Objective: To assess the factors associated with delivery greater than or equal to 28 weeks' gestation after placement of an emergent cerclage in women with singleton gestations.
Methods: All women who underwent emergent cerclage, defined as any cerclage placed between 16 and 24 6/7 weeks' gestation in response to documented cervical change on physical examination, at Northwestern Memorial Hospital from 1980 to 2000 were identified. Univariable and multivariable analyses were used to determine the factors most associated with achieving at least 28 weeks' gestation.
